The Portable Echo Sounder is a low cost ultrasonic water depth instrument meter, which is have the GPS function, could measure Latitude, Longitude, Altitude, used for measuring water depth in silting or sedimentation studies, dredging surveys in lakes, rivers, ports, sea, and inshore hydrographic surveying. These are also applicable in testing aid for electronic servicing, research and development, education, etc. The instrument can be used as a conventional echo sounder with depth data output via an LCD screen and printer.

This depth meter adopt the ultrasonic principle, have perfect function to measure the water depth, and control, data tranmit, communication. The unit is sold as a complete package and includes transducer, handheld terminal, internal battery charger, and protect box.
